I did say AK will get 15 million in 2017. That is not without additions. Pandora, Rivers of Light and the night time safari will all be running by then. As for DHS the star wars addition will draw so many more customers than HP2. They still sell 10 million light sabers a year. That is before the new star wars movies come out. Yes DHS will draw 15 million a year. As for Epcot I said they need some upgrades in both world.show case and future world but yes they can and will draw 20 million in 2021. I don't believe I said it would be in 2017 and if I did I apologize. The same goes true for the Magic Kingdom, the 25 million will be in 2021. Do you really doubt that on their 50th anniversary they will not draw 7 million more than in 2013? You seem to think that Pandora and the rest of AK expansion will be canceled and nothing else will be built between now and 2021. If you really believe that you are alone.
You do realize all of those additions to AK only bring 2 attractions to the table? Animal Kingdom is at 10 million right now.. I'm expecting it to stay even for the next 3 years... so 10-10.5 million by 2017. It's not possible for a low-hype IP like Avatar to bring in 5 million guests. River of Lights and nighttime safari will help, but not 5 million guests... do you know how awful the lines at AK would be if 5 million guests were added to the attendance each year? a 45 minute wait would almost be a walkon
12 million-12.5 million is feasible by 2021. But compared to Potter and Star Wars, Avatar just isn't gonna turn the stiles.
Star Wars will only draw more customers if Disney does it right... a spinner, M&G, restaurant and Omnimover won't get DHS to 15 million. DHS can't even hold 10 million without the park feeling unnecessarily packed. Toy Story Mania shouldn't ever have a line about 45 minutes, yet it gets 3 hr waits regularly. ToT gets 90-120 minute waits, same with RnRC. Even Star Tours gets 30-40 minute waits and it's a people-eater.
DHS has less capacity than USF and IOA... yet you act like it can add 5 million guests over a single year (2019 is the earliest any Star Wars expansion would open considering how slow TDO is with construction). 6 rides... 5 shows. 2 of which could very well be closed during Star Wars construction. 11 attractions, yet you think it has more capacity than USF and IOA which have 50 between them?
You know what? Epcot COULD get to 20 million if TDO actually bothered to overhaul Future World, add original E-tickets and add stuff to World Showcase you can ride/watch. But you know what? TDO shows ZERO interest in that. There's 11 empty expansion pads at Epcot waiting for additions. And one empty pavillion used for corporate meetings. TDO has not shown they want Epcot to get to 20 million. If they did, they would have taken the $2 billion from MM+ and invested into fixing the park. Again, 13-13.5 million is more reasonable since the only things Epcot may be getting (Imagination revamp, extra Soarin' theater, Energy upgrade) just is far too little, far too late. I love Epcot, but sadly 20 million isn't happening until every last expansion pad is full and the Wonders of Life pavillion is occupied with attractions again.
MK isn't adding 7 million guests over 7 years... MAYBE 2-2.5 million over 7, but nowhere near 7 million. SDMT is the last major addition the park is getting until 2021 at the earliest (Tomorrowland redo or Frontierland expansion - and that's not even close to certain). Do you know how unbearable the park would be with 25 million guests? The lines and paths are already packed to the brim - imagine 7 million extra people. Unless the entire backstage area is reworked to allow construction beyond the railroad berm, that's not happening.
You clearly haven't looked up the attendance trends for WDW for the last 10 years. Go look up the TEA numbers - though, guest spending and other factors are more important than attendance. MK has dipped and risen by less than 5% except for when New Fantasyland opened.
Have you bothered to look at what Universal Orlando has planned? Do you think we're just saying it'll have large increases for our health? Kong + Diagon Alley + KidZone replacement... and that doesn't include CityWalk 2.0, hotel 5, the waterpark, and other additions. Universal is giving the guest what they want.
Honestly, I'm tired of arguing like this. It's petty. You've clearly succumbed to pixie dust - and there's no turning back for you. As a fan of Disney and Universal alike, I criticize and praise when the situation warrants it. Dragon Challenge's lack of theming on the ride itself and the FJ show-building are two fatal flaws in Hogsmeade I want Universal to fix. Likewise, TDO should aim to fix up Epcot, DHS and AK before the 50th. I get that Pandora is going to be a nice addition - but there's no excitement when the big E-ticket is a 3D version of Soarin'. I'm exciting for the indoor boat ride! That's something AK needs desperately - and I appreciate TDO for adding it.
Universal is also smaller at the moment... with 15.1 million combined attendance. IOA is getting an increase just because of Hogwarts Express. USF gets the huge boost because of Diagon Alley. Also, you have to consider that Transformers and Springfield will still be driving attendance slightly as well since this is their first full year.
8.5 million for each would only be 17 million combined. Surely not as ludicrous as you claiming that Pandora will add 5 million in a year or that just Star Wars Land will get DHS past 15 million (you even said the park can't hold more than 12 million - SWL would only add another million in capacity... you'd have to do a Pixar Place expansion using Backlot Tour and LMA in order to get to 15 million)
Again, you obviously aren't going to change your mind, so I'll let you retire to WDW: where stagnant parks MAGICALLY add 5 million to 7 million guests in one year.
, it also increased to 7.1 million just like the one down the highway from WDW. And it got over 8.5 million last year. Certainly possible for USF and IOA - both of which are leaps and bounds above DCA. 
). You also don't seem to get TDO just wasted $2 billion on Magic Bands and Fastpass+. They aren't going to be building these E-tickets it would take to add the supposed 5 million you're coming up with. Whereas Universal will just be getting to $1 billion spent in Orlando (maybe a little over) once Kong opens. That includes Transformers, Springfield, Diagon Alley, Cabana Bay, Citywalk 2.0 and Kong.
personally, I'd like to see them return to their rightful firehouse in New York.
